HOSE-COUPLING.

Specification of Letters Patent. Patented June 15 1915 Application filed.Tune 24, 1914'. Serial No. 847,089.

To all whom it may concern Be it known that I, ALBERT RELI'rz, a citizenof the United States, residing at Retah, in the county of Dawson andState of Montana, have invented certain new and useful Improvements inHose-Couplings, of which the following is a specification, referencebeing had to the accompanying drawin s. v

lhis invention relates to new and useful improvements in hose couplingsand more particularly to a quick detachable coupling, the main object ofthe present invention being the provision of a hose coupling of theabove character whereby two sections of hose may be quickly and readilyattached together or detached, or wherein one sect on of hose may bequickly and readily attached to a hydrant or other supply source.

Another object of the present invention is the provision of a hosecoupling of the above character which will possess advantages in pointsof eflicienoy and durability, is inexpensive to manufacture and, at thesame time, is simple in construction and operation.

With the above and other objects in view, the invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification and claims.

In the accompanying drawing forming a part of this application, Figure lis a longitudinal sectional view of a hose coupling constructed inaccordance with my invention, illustrating parts thereof in their lockedposition. Fig. 2 is a side elevation of the device in its disconnectedstate. Fig. 3 is an end elevation of the male portion of the coupling;and Fig. 4 is an end elevation of the female portion.

Referring more particularly to the drawing, 1 indicates the femalesection of my improved hose and the numeral 2 indicates the malesection. The female section 1 is provided with a substantiallyfunnel-shaped mouth 3 adapted to receive the outer conical end 4: of themale section 2. The outer end of the funnel-shaped mouth 3 is providedwith a shoulder 5 and formed contiguous with the shoulder is an annularrecess 6 terminating in a shoulder 7, the purpose of which will behereinafter more fully set forth. Formed upon the male section 2, is anannular flange 8 which is adapted to be arranged within the mouth of thefemale section and mounted upon the cone-shaped portion 4 and bearingagainst the flange 8, is a washer 9, the outer periphery of which isadapted to be yieldably arranged within the recess 6 of the femalesection and retained therein by means of the shoulder 7.

In order to retain the hose section against rotary movement, withrespect to each other, suitable recesses 10 are formed in the outer edgeof the mouth 3 and arranged in opposed relation for the reception of theoppositely disposed lugs 11 formed upon the male section 2. These lugs11 are securely retained within the recesses 10 by means of an ovalretaining member 12 formed of two separable sections, preferablysemi-oval in form, the ends of which are arranged at right angles to thebody portion and one end of each of the sections being pivotallyconnected to the ear 13 which is formed upon the outer surface of themouth portion 3. Pivotally connected to the ear 14: which is formed uponthe mouth portion 3, opposite the ear 13, is a lever 15 which ispivotally connected to the outer ends of the members forming theretaining member 12 by means of the links 16.

From the above it will be apparent that in connecting the two hosesections together, the cone-shaped portion of the male section isinserted within the mouth 3 of the female section and pressed inwardlyuntil the washer 9 engages within the recess 6. It will be noted that inplacing the male section within the mouth of the female section, thelugs 11 will be disposed at right angles with respect to the positionthey assume after the funnel member has been inserted within the mouth.After the male section is in position, the lever 15 is actuated toengage the side portions of the member 12 with the lugs and force theminto the recesses 10, so as to retain the hose sections against rotarvmovement and also against longitudinal movement. It will be noted thatby having the central portions of the link members 16 bowed, as shown at17, they will be disposed upon opposite sides of the ear 14, when thedevice is in its closed position and assist in retaining the lever inits locked position and prevent the same from becoming accidentallyunlocked.

From the above it will be noted that I have provided a simple anddurable hose coupling whereby two sections of hose may be quickly andreadily connected together or disengaged and wherein one section of hosemay 7 be quickly connected to a hydrant or detached therefrom. It willalso be apparent that the device is extremely simple in construction andcan be manufactured of such material that the same may be placed uponthe market at a comparatively low cost.

While I have shown and described the preferred form of my invention, itwill be obvious that various changes in the details of construction andin the proportions may be resorted to for successfully carrying myinvention into practice, without sacrificing any of the novel featuresor departing from the scope of the invention, as defined by the appendedclaims.

Having thus described this invention, what I claim is 1. A device of theclass described including a'female section having a funnel-shaped mouthportion provided at its outer end with opposed recesses, a male memberhaving a cone-shaped end adapted to be inserted within the funnel-shapedmouth, opposed lugs formed on said male member adapted to be arrangedwithin said recesses, and movable means carried by the female sectionadapted for engagement with the lugs to retain the sections in theirlocked positions.

2. A device of the class described including a female member having afunnelshaped mouth, an annular shoulder formed therein, said mouth beingfurther provided with a recess contiguous with the shoulder, said mouthhaving opposed recesses formed in the outer end thereof, a male member,op

' posed lugs formed on said male member and adapted to be disposedwithin said recesses, an oval-shaped retaining member pivotally mountedupon the outer end of the female member adapted for engagement with saidlugs to retain the sections in their eflective position, and meanswhereby to actuate said retaining member to secure the same in itslocked position.

3. A device of the class described including a female member having afunnelshaped mouth portion and provided with opposed recesses at itsouter end, an annular shoulder formed within said mouth portion,

a retaining rib formed at the outer end of the sections, an oval-shapedretaining member having one end pivotally connected to the funneLshapedmouth portion, an actuating lever pivotally connected to the oppositeside of the funnel-shaped mouth portion, and link members pivotallyconnecting the outer end of the retaining member with the lever, wherebysaid retaining member will be manually forced against the lugs to retainthe same within the recesses and prevent rotary or longitudinal movementof the coupling sections. a y

4. A' device of the class described including a female section having amouth portion provided at its outer end with recesses, a male memberadapted to be inserted within the mouth,lugs formed on said malememberadapted to be arranged within said recesses, and movable means carriedby the female section adapted for engagement with the lugs to retain thesections in their locked position. p i v a In testimony whereof Ihereunto affix my signature in the presence of twowitnesses.
